“…It has been demonstrated that XLPE nanocomposites can improve electrical properties [12][13][14][15][16][17]. The interface in nanocomposites between the polymer matrix and nanoparticles is the main reason for the improvement in the electrical properties [18][19][20][21][22][23][24]. To understand the characteristics of this interface, some microscopic models have been proposed, such as the multi-core model [25][26].…”

The interface between nanoparticles and the polymer matrix, which dominates the electrical properties of nanocomposites, can effectively improve the DC breakdown and suppress space charge accumulation in nanocomposites. To research the interface characteristics, XLPE/SiC nanocomposites with concentrations of 1 wt%, 3 wt% and 5 wt% were prepared. The DC breakdown, dielectric properties and space charge behavior were examined using pulsed electro-acoustic (PEA) equipment and a dielectric analyzer. The test results show that the nanocomposites with concentrations of 1 wt% and 3 wt% have higher DC breakdown field strength than neat XLPE. In contrast, there is a lower DC breakdown strength at a concentration of 5 wt%, possibly due to the agglomeration of nanoparticles. Nanoparticle doping increases the real and imaginary permittivities over those of neat XLPE. Furthermore, with increasing concentration, a larger increase in the permittivity amplitude was observed. Based on the space charge behavior, all nanocomposites could suppress space charge accumulation, but the nanocomposite with a concentration of 1 wt% exhibited the best effect. Meanwhile, heterocharge accumulation near electrodes was observed in neat XLPE and the nanocomposite with a concentration of 5 wt%. In contrast, homocharge accumulation near electrodes was observed in the nanocomposite with a concentration of 3 wt%. This phenomenon may be due to different amounts of shallow traps in nanocomposites with different concentrations, which might lead to differing electron or hole mobility.

“…18 Yoshikazu realized the surface modification of silica particles with polyimide. 19 In the present work, an attempt was made to achieve the surface modification of TiH 2 with an epoxy resin by using a custom ultrasonic wave-assisted ball milling device. Our previous studies have shown that the coupling effect of ball milling and ultrasonic wave can promote the preparation of ferrite nanoparticles by improving the reactivity of the raw material and decreasing the incubation period of the chemical reaction.…”

Surface modification of titanium hydride (TiH 2 ) with epoxy resin was carried out by ultrasonic wave-assisted ball milling. The product was characterized by X-ray diffraction, transmission electron microscopy, thermogravimetry and Fourier transform infrared spectroscopy. The sedimentation test was conducted to investigate the compatibility of TiH 2 nanoparticles with epoxy resin. The results show that epoxy resin is grafted on the nanoparticles' surface after the ultrasonic wave-assisted ball milling process, which improves the compatibility of TiH 2 nanoparticles with epoxy resin. The different results of ultrasonic wave irradiation, ball milling (without ultrasonic wave assistance) and ultrasonic wave-assisted ball milling indicate that the coupling effect of ultrasonic wave and mechanical force plays an important role in the grafting process. In addition, the anticorrosion property of epoxy resin coating containing modified nanoparticles was investigated.

“…Although, there are few research works dealing with CSM rubber and especially its nanocomposite, the effect of some fillers such as carbon black and nano clays on physico‐mechanical and electrical properties of CSM vulcanizates has been studied. The systematic study of the CSM rubber filled with nano‐and micro‐silica particles has not received much attention till now .…”

“…CSM as a component of polymer blends has been studied extensively, but in some applications it is necessary to use it alone. The literature have almost exclusively focused on blends of CSM and there are rare reports on CSM rubbers alone . Since this rubber possesses good electrical, weather and chemical properties, in some application such as nuclear plant cable sheath it should be used alone .…”

In this study, the effect of micro and nano silica and their combination on mechanical and thermal properties of Chlorosulfonated Polyethylene compounds were investigated. Cure characteristics were studied using a Monsanto Moving Die Rheometer at 1558C. Incorporation of nano silica accelerated the vulcanization whereas the micro silica particles decelerated the curing process. Both micro and nano silica increased the crosslink density as evidenced by swelling test. However, this value has been more improved in CSM/nano silica composites. The physico-mechanical properties of CSM/nano silica are superior compared to CSM/micro silica. Nano silica provided reinforcing efficiency which is not only because of higher specific surface area but also because of various interactions and especially physical interactions which are discussed in the text. Nano silica particles also improved the thermal properties more efficiently. Incorporation of 15 phr (part per hundred) nano and 5 phr micro silica to polymer improved the initial decomposition temperature for about 518C and 168C, respectively, using a TGA. The combination of micro and nano silica, showed that by coupling nano and micro fillers, the loading of fillers can be minimized. In other words, the hybrid samples with a lower filler loading behave as efficient as their separate counterpart with higher loading.
